ROPE-SOCKET.

l SPECIFICATION forming part of Letters Patent No. 761,396, dated May31, 1904.' Application led July 22, 1903. Serial No. 166,611. (Nomodel.)

To all whom t may concern.-

Be it known that I, CHARLES PETERS, a citi-- zen of the United States,residing at Nampa, in the county of Canyon and State of Idaho,

have invented a new and useful Rope-Socket, of

which the following is a specification.

This invention relates to devices for coupling" the ends of ropes todrilling-tools or other fixtures, and is applicable more particularly towell-drilling apparatus, but which may also be employed wherever it isdesired to couple a rope'or cable to a chain or other device.

The invention consists in a tapered socket screw-threaded at its largervend and carrying means for the attachment of the drill-tool at.

l specied in the claims following.

In the drawings illustrative of the invention, Figure 1 is a verticalsection of the device.

Fig. 2 is a 'transverse section on thel'ine 2 2 for rotating it, wherebythe head may be adjusted in the socket. Within the socket are disposedtwo opposing tapered segmental plates 1313, the two plates when combinedforming a tapered divided sleeve, as shown. Extending from the interiorsof the plates 13 13 are spurs 14, as shown.

The rope or cable is indicated at 15 and will beenclaspedat its end bythe plates 13 13,

with the spurs extending into the. cable to firmly clamp it between theplates.

When the device is to be used, the head 12 will be passed over the endof the rope or cable and the plates 13 13 placed upon opposite sides ofthe end of the cable below the head 12. The plates 13 13 will not meetat their adjacent edges, as indicated in Fig. 2, so vthat when insertedinto the socket with the cable between them and vthe head member screwedhome in thesocket the plates will have ample room inwhich to becontracted around the cable when forced downward into the taperedsocket. By this means the cable will be very iirmly clamped between theplates and rigidly united to the socket member.Y

While twoof the tapered plate members 13 13 are shown, I do notdesire'to be limited to this number, as a change in this particularwould not be a departure from the principle of the invention. l

The device maybe constructed tot anysized rope or cable andv willY forma very eilicient implement for the various purposes for which similardevices are-employed. -Its extreme simplicity and ease of applicationand great strength of grip will make it a very eflicient and valuabledevice.

Where ropes of smaller diameter than the socket are to be employed inconnection therev with, I prefer to use an auxiliary sleeve l16,

which may beplaced within the head 12, and said sleeve is provided witha flange 17, extending under the head and engaging the plates 13 13.This is plainly illustrated in Fig. 3.

Having thus described my invention, what 'clamp members havinginwardly-extending spurs to engage the cable, and a sleeve slidable onthe cable and having an externallyscrew-threaded reduced end adapted toengage with said threaded socket and having a shoul- IOO der adapted toabut against the outer edge of the socket with the inner edge of itsreduced end abutting against the outer edges of the elamp members toexert a longitudinal force upon said tapered clamp members to move themforcibly into said socket.

2. A clamp comprising a socket member ared toward one end, a pluralityof clamping members having inwardly-extending cable-engaging spursadapted to penetrate the Cable and hold said clamp members firmly inconnection therewith, a sleeve loosely engaging
